DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 405,362, dated June 18, 1889.

Application filed June 19, 1888. Serial No. 277,602. (No model.)

To all whom it may concern.-

Be it known that I, BERNARD KILLEEN, a citizen of the United States, residing at Big Rock, in the county of Scott and State of Iowa, have invented anew and useful Dumping-WVagon, of which the following is a specification.

My invention relates to improvements in dumping-wagons in which the bottom of the wagon-box is made in transversely-arranged sections or flaps hinged at opposite outer corners to the lower edges of the side-boards of the box, the opposite outer corners being suspended by chains or straps to longitudinal slide-bars parallel with the sides of the wagonbox; and the object of my improvements is to provide means for expeditiously dumping the contents of the wagon-box. I attain this object by the mechanism illustrated in the ac-- companying drawings, in which E. Figure 1 is a side view of the dumpingwagon, the two wheels on the left-hand side of which are removed. Fig. 2 is a view of a transverse vertical section on the line 00 a: of Fig. 1, looking in the direction of the front of the wagon, the front wheels being removed. Fig. 3 is a longitudinal vertical section of the view shown in Fig. 2 upon the line y y, looking in the direction of the right-hand side of the wagon. Fig. 4 is a view of cross-section of one of the side-boards of the wagon-box and parallel slide-bar with side view of roller upon which the latter rests. Fig. 5 is a side view of the section of the wagon shown between the lines 1, 2, 3, and 4 in Fig. 1; and Fig. 6 is a view of a portion of one of the hinged sections or flaps which form the bottom of the wagon-box.

Similar letters refer to similar parts throughout the several views.

The letters A represent the wheels of the wagon, B the front axle, and O the rear axle.

D is the tongue attached to the front axle.

The letter a represents the lower front bolster, and l) the upper front bolster; c, the lower rear bolster, and d the upper rear bolst-er.

The letters e 6 represent braces rigidly attached between each of the bolsters a and b and thebolsters c and (Z. The braces attached between the bolsters c and cl are not shown in the drawings, as the form of the braces and method of attachment are the same as between bolsters a and b; but, however, in Fig. 1 the end of brace e is shown.

E is the kin g-bolt, riveted or bolted through its head upon the under side and at or near the center to bolster I), said king-bolt extending downward through bolster a and below the bottom of axle B. On the bottom of bolster a is the washer f, through an aperture in which extends said king-bolt.

A stirrup F is fitted over the top, bottom, and front sides of axle B at or about its center, the horizontal arms of which stirrup extend beyond the rear side of said axle, so that the lower part of king'bolt E may pass vertically through perforations therein. Stirrup F is held in position by the bolt and nut g.

' The lower rear bolster c is rigidly attached to the upper surface of axle O.

The letters G represent the side-boards of the wagoirbox', and the letters II the endboards of the same. The lower edges of the side-boards of the wagon-box rest upon the upper surface of the bolsters b and d, and are rigidly secured thereto by the braces S. The wagon-box is further strengthened and supported by beams I I, to which the side-boards are in the same manner secured by similar braces S, butwhich are not shown in the drawings. From each of the outer surfaces of sideboards G project rollers h, each secured to the side-board by a bolt and nut i. These rollers h extend in two parallel lines lengthwise of said side-boards, being sufflciently apart to accommodate between them slidebar J upon each of said sideboards. Near the front end of said wagon-box is the transversely arranged crank shaft, its extreme ends passing through perforations in said side-boards, thus forming journals for it to rotate in, and which crank-shaft is designated in the drawings by the letter K. The ends of this shaft outside of the wagon-box have attached elbows or cranks It It, and to the lower end of each are loosely pivoted the bars jj, the rear ends of each of which are loosely pivoted to the outer sides of one of said slidebars J. 011 one side of crank-shaft K is attached a vertical handle Z, provided with a catch-lever and bolt m to operate and engage with the notches in segment 92, attached to one of said side-boards G. On the lower and outer surface of said side-boards G are attached the hooks 0. The sections or flaps L are made the width of the wagon-box and as long and thick as shall be found desirable. At opposite corners, upon one side of each of said flaps L, extend trunnions p p, which enter the hooks 0 upon opposite sides of the swung downward as they appear immediately after dumping the contents of the wagon-box. Referring to this figure,'the operator, by grasping with his hand the handle Z and pulling the same backward, causes the crankshaft K to partially rotate and the ends of cranks k to move forward, carrying forward, also, bars j j and slide-bars J J. The movement forward of slide-bars J J causes the respective chains or straps to move forward over their respective pulleys q and to raise or swing upward each of the respective flaps L until they come in contact with the surface of the lower edge of each of said sideboards G of the wagon-box, when the operator causes the catch-lever and bolt on on handle Z to engage in the notches of segment 11, thus locking and holding the flaps L in said position.

When the operator desires to dump the contents of the wagon-box, he disengages the catch-lever and bolt on from the notches in segment a and moves the handle Z forward, and the opposite movement of the parts takes place from that above described.

I am aware that prior to my invention dumping-wagons have been described in which the bottom of the wagon-box was composed of transVersely-arranged flaps or sections having trunnions at the sides near. the outer ends journaled into bearings on the lower edge of the sides of the wagon-box, the free ends of which were connected by operating-rods to a lever for the purpose of swinging the flaps upward to form a bottom for the box, and having attached to said lever a device for looking it, and thus holding the flaps in position. I am aware that such box was intended for use upon running-gear not connected by a reach.

I do not broadly claim the feature of a king-bolt in the rear of the front axle, because I am aware that such has been described in connection with an upper circular plate horizontally attached to the under side of the bolster or head-block having a lug extending in the rear of said axle, an under circular plate horizontally attached to the top of the axle-bed upon said axle having a lug extending in the rear of said axle, a brace, its forward end bolted to the'front part of the upper circular plate, its forward projecting end supporting the front part of the under circular plate, such brace extending rearwardly therefrom and secured to the under side of said axle, with a further rearward projection back of said axle and said lugs and rearward projection of said brace back of said axle, each perforated in a vertical line to accommodate said king-bolt. Such construction is substantially described in Letters Patent No. 345,585 to Greer, July 13, 1886. I place the king-bolt in the rear of the front axle to permit the axle to swing thereon; but Iuse a more simple and practical device to accomplish such result. I do not use the forward-projecting upper and under circular plates respectively connected with the bolster and axle, nor the forward-extending brace supporting such plates. vI use simply rear projections rigidly attached to the top and bottom surfaces of the axle, each perforated in vertical line to accommodate the king-bolt, and for strength only I connect the forward ends of the projections, thus forming a stirrup. A washer is fitted over the kingbolt between the lower bolster and the perforation of the upper rear projection, so as to raise such bolster in a horizontal line above the upper horizontal surface of the axle to avoid contact in swinging.

I am aware that a longitudinal bar has been described as supported in suitable guides on the side-board of a dumping-wagon arranged to be moved forward and backward by a suitable handlever; that the floor of such wagon-box is described as composed of transverse slats, their pivots projecting through the side-board, having at the end crank-connection with such longitudinal bar, whereby such slats could be caused to turn with their pivots from a horizontal position to a vertical, and vice versa. Such construction is described in Letters Patent No. 233,049 to Townsend, dated October 5, 1880. I am also aware that where hinged transverse slats are used to form the floor of the wagon-box and a longitudinal bar supported in guides upon the side of the wagon-box, arranged to be moved forward and backward by a suitable hand-lever, that mechanism for turning such slats upon their pivots from a horizontal to a vertical position, and vice versa, has been described, in which the outer ends of the pivots are bent at right angles, forming a crank to engage suitable cams on said longitudinal bars. I do not claim such features, broadly, but limit myself to the specific structure in the various combinations which I have described, which are more simple and less liable to disarrangement than other devices now known.

While I use transverse flaps or slat-s hinged to the side-boards to form the floor of the wagon-box and longitudinal bars supported in roller-guides on the side-boards actuated by a hand-lever, yet I combine with these a transversely-arranged crankshaft, whereby the longitudinal bar upon each sideboard is connected, thus imparting similar longitudinal movement to each bar through the hand-lever. I connect the free sides of each transverse flap to the longitudinal bars by means of straps or chains moving over rollers at the lower edge of the side-boards. By releasing the segmentcatch upon the handlever the Weight of the earth or other material upon the flaps when in a horizontal position causes them to swing downward auto-' matically, and also moves the longitudinal bars upon their roller-supports sufficiently to permit such action. The operator has only to use manual power against the lever when raising the flaps from a vertical position to a horizontal position, which is thereafter maintained through the catch engaging the notches upon the segment.

WVhat I claim as my invention, and desire to secure by Letters Patent, is

1. In a dumping-wagon Where each of its two box-sides supports in suitable guides a longitudinal slide -bar, mechanism substantially as described, for lowering the free edge of the pivoted transverse flaps form ing the floor of such boX when horizontal to a vertical position, and Vice versa, in combination with a transverse shaft journaled through such box-sides, a crank-arm on each end of such shaft outside of said box, a vertical handle rigidly attached to said shaft carrying a catch-lever and bolt to engage with the notches of a segment attached to one of the sides of said box, and each of such longitudinal bars connected to the end of one of such cranks by an intermediate pivoted bar, for the purposes stated, and substantially as described.

2. In a dumping-wagon, the front axle provided with the stirrup F, combined with the king-bolt attached to the upper and lower bolster, the lower part of said king-bolt passing vertically through suitable apertures in the upper and lower arms of said stirrup and at the rear of said axles, substantially as described.

3. In a dumping-wagon where each of its two box-sides supports in suitable guides a longitudinal slideb'ar, mechanism, substantially as described, for moving such bars forward and backward, and such box provided with transverse flaps trunnioned thereto, substantially as described, and arranged to swing from a vertical to a horizontal position, and vice versa, in combination with the chains or straps 0", running over pulleys q on said box-sides and connecting said transverse flaps with said longitudinal bars, for the purposes stated, and substantially as described,

BERNARD KILLEEN.
